Hi, I just finished making a program to use EEPROM. After the read and write is complete, I execute this: movwf TXREG ; send it sleep ; die off bsf porta,2 Now, when I run the program, the LED on porta,2 comes on!!. Am I just misinterpeting the sleep instruction (it sort of turns off the PIC, right?). I double checked that the watchdog timer is off.
